Definitions

  • the present invention relates to oil and gas well drilling and more particularly to the handling of cuttings that are generated during oil and gas well drilling activity. Even more particularly, the present invention relates to an improved vacuum tank apparatus for use in handling cuttings that are generated during oil and gas well exploration.
  • the tank has a specially configured hopper that communicates with an outlet header that enables air to be injected during the discharge of cuttings from the tank.
  • a drill bit In the drilling of oil and gas wells, a drill bit is used to dig many thousands of feet into the earth's crust.
  • Oil rigs typically employ a derrick that extends above the well drilling platform and which can support joint after joint of drill pipe connected end to end during the drilling operation.
  • additional pipe joints are added to the ever lengthening "string" or "drill string”.
  • the drill pipe or drill string thus comprises a plurality of joints of pipe, each of which has an internal, longitudinally extending bore for carrying fluid drilling mud from the well drilling platform through the drill string and to a drill bit supported at the lower or distal end of the drill string.
  • Drilling mud lubricates the drill bit and carries away well cuttings generated by the drill bit as it digs deeper.
  • the cuttings are carried in a return flow stream of drilling mud through the well annulus and back to the well drilling platform at the earth's surface.
  • the drilling mud reaches the surface, it is contaminated with small pieces of shale and rock which are known in the industry as well cuttings or drill cuttings.
  • shale shakers have in the past been separated from the reusable drilling mud with commercially available separators that are know as "shale shakers".
  • Other solids separators include mud cleaners and centrifuge. Some shale shakers are designed to filter coarse material from the drilling mud while other shale shakers arc designed to remove finer particles from the well drilling mud.
  • the drilling mud is returned to a mud pit where it can be supplemented and/or treated prior to transmission back into the well bore via the drill string and to the drill bit to repeat the process.
  • Drill cuttings contain not only the mud product which would contaminate the surrounding environment, but also can contain oil that is particularly hazardous to the environment, especially when drilling in a marine environment.
  • Safeguard Disposal Systems, Inc. of Lafayette, Louisiana has manufactured, sold, and used publicly a cuttings disposal tank that includes hatch openings into which oil well cuttings can be placed.
  • These prior art tanks also have attachments for enabling lift lines to be affixed to the tank so that it can be transported to and from offshore platforms and emptied when full. Further examples of these tanks are shown in one or more of the following United States Patents: 5,564,509; 5,402,857; Des. 337,809; and Des. 296,027.
  • U.S. Patents 5,564,509 and 5,402,857 are incorporated herein by reference.
  • the present invention provides and improved vacuum tank apparatus that can be used to vacuum drill cuttings on an oil and gas well drilling rig through an open top hatch portion of the apparatus and then to discharge those cuttings through an outlet header using suction applied to the outlet header as well as compressed injected air that is transmitted to the outlet header.
  • the apparatus includes a frame having a plurality of comers reinforced by structural comer columns, a generally horizontally extended base that includes a plurality of base perimeter beams, and an upper end portion of the frame that includes a plurality of upper perimeter beams. The columns are structurally interconnected to both the upper perimeter beams and the base of the frame.
  • a shaped hopper is supported by the frame internally of the perimeter beams.
  • the hopper includes and interior and sidewalls that are comprised of a plurality of inclined sidewall sections, each inclined wall section including an upper end portion that connects to the frame at the perimeter beams and a lower end portion that extends to another lower end portion of another inclined wall section.
  • the two lower end portions of the inclined wall sections that are joined meet at an outlet header at the bottom of the hopper.
  • This outlet header is mated to the lower end portions of the inclined wall sections and includes a discharge outlet for discharging material from the hopper interior via the outlet header.
  • the top wall of the hopper has multiple hatches including a first hatch near a first perimeter beam and a second hatch next to another perimeter beam that is parallel to the first perimeter beam.
  • the outlet header includes opposed open end portions that are fittings for directing fluid flow.
  • One of the end portions is an air inlet for injecting air into the outlet header.
  • the other end portion of the outlet header defines a fitting for connecting a suction line thereto.
  • a secondary air fitting for enhanced cleanout and material transfer can be provided at the discharge fitting.
  • the outlet header thus preferably comprises a longitudinally extended trough portion with an open top that communicates with the interior of the hopper.
  • a pair of opposed end portions of the trough have fittings for attaching flow lines to the outlet header.
  • the outlet header thus defines a closed structure with the lower end portion of the hopper and the fittings so that a vacuum can be held on the tank when the outlet header is not being used.
  • the outlet header preferably provides valves at each end portion next to the two fittings so that the flow of air into the outlet header can be valved. Additionally, the discharge of solid material from the outlet header can also be valved.
  • the apparatus of the present invention eliminates the dangerous and messy practices of lifting and/or tipping the tank frame on an oil rig in order to empty the tank contents.
  • the inclined walls of the hopper remove any need to tip or lift the tank during emptying.
  • the hopper is configured to completely empty of material using a vacuum and without tipping or lifting thus eliminating a crane or cranes.
  • FIGS 1-4 show the preferred embodiment of the apparatus of the present invention designated generally by the numeral 10 in Figures 1-4.
  • Vacuum tank apparatus 10 is supported by a structural frame 11.
  • the frame 11 holds a hopper 35 that is comprised of a plurality of hopper walls 12,13,14,15.

  • the elbow 24 carries a ball valve 25 that can be opened and closed.
  • Each of the hatches 17, 18 is mounted to the top plate 16 using hinges 27, 28 respectively.
  • a closure 29, 30 can be respectively provided for each hatch 17, 18 in the form of a cammed rod such as the rods 39, 40 shown in Figure 3.
  • ring nuts and bolts can be used to close hatches 17, 18.
  • Frame 11 is comprised of a plurality of base beams 31, column beams 32 and upper perimeter beams 33 as shown in Figures 1-4. These respective beams 31, 33, and column 32 form a rectangular block-like enclosure that protects hopper 35 during transportation.
  • the base perimeter beams 31 can additionally be provided with plate for decking if desired.
  • Left and right sockets 41, 42 define receptacles for fork lift tines at each perimeter beam 31 so that the apparatus 10 of the present invention can be lifted and transported using a fork lift if desired.
  • Each of the column beams 32 occupies a comer of the frame 11 as shown in Figure 1-4.
  • Each column beam 32 provides a stacking pin 34 at its upper end portion as showing in Figures 1-4 and 7.
  • a correspondingly shaped socket under each column 32 at a perimeter beam 31 receives a stacking pin 34 when one tank apparatus 10 is stacked upon another tank 10.
  • Lifting eyes 79 and slings can be attached to tank apparatus 10 for enabling a crane to lift the apparatus 10 during transfer to and from the drilling rig.
  • the frame 11 can also includes additional intermediate horizontal beams 43 and vertical beams 44 that define an interface in between selected ones of the base beams 31, column beams 32 and upper perimeter beams 33.
  • the intermediate perimeter beams 43 are generally parallel to and below upper perimeter beams 33.
  • Each intermediate beam 43 connects to and spans between two columns 32 as shown in Figures 1,2 and 4.
  • hopper walls 12, 13, 14, 15 At least two of these walls 12, 13 (and preferably all four walls 12-15) converge to form a connection with outlet header 50.
  • Stiffners 77 can be welded to the walls 12, 13, 14, 15 for strengthening them.
  • the walls 12, 13, 14, 15 each include inclined sections in between beams 31 and 43.
  • the hopper 35 is thus shaped to enable complete emptying and discharge of drill cuttings and like material using a source of vacuum and without having to tip or lift the tank.
  • the present invention eliminates the need for manual labor to shovel or scrape material to header 50.
  • Each of the walls 12, 13, 14, 15 has a vertical section between beams 43 and 32.
  • Outlet header 50 is shaped to facilitate discharge of material contained in hopper 35, shown in figures 1, 2, 4, 5, 8, 9, and 10.
  • the outlet header includes a channel section 46 that is connected to the lower edge 47 of wall 12 of hopper 35 and to the lower edge 48 of wall 13 of hopper 35 as shown particularly in figures 4 and 5.
  • the channel section provides a U - shaped trough in transverse cross section.
  • the upper edges 49, 51 of channel section 49 are connected (e.g. welded) to the lower edges 47, 48 of sides 12, 13 of hopper 35.
  • an inlet fitting 52 is provided at wall 15 of hopper 35 for injecting air under pressure.
  • the fitting 52 can be a cylindrically shaped member having a central longitudinal bore with a central longitudinal axis that aligns with the central longitudinal axis 54 of channel section 49.
  • Valve 55 can be positioned on the inlet 56 side of fitting 52 for closing the flow via fitting 52 to channel section 49. Upstream of valve 55 is a quick connect member that enables an air hose to quickly be connected to the assembly of fitting 52, valve 55 and quick connect member 57.
  • compressed pressurized air can be injected into header 50 for assisting in the movement of material that flows by gravity from hopper interior 38 to a discharge hose 81 and then to a second vessel 82.
  • a second vessel 82 can be a cuttings collection and disposal tank such as shown and described in my prior U.S. Patent Nos. 5,564,509 and 5,402,857. This flow of pressurized air and material is indicated by arrows 58 in figures 1 and 8-10.

  • a spool piece 66 with an open ended bore 70 can be fitted to flange 65 for transmitting material from hopper interior 38 via fitting 59 to a suction hose line 78.
  • Fitting 71 on spool piece 66 can be used to couple an air line to the spool piece 66 as an additional means of moving material into discharge line 80 that is being removed from hopper 35 via outlet header 50.
  • the spool piece comprises larger diameter section 67, transition section 68 and smaller diameter section 69.
  • the outlet header 50 is closed by shutting valves 55 and 63. Drill cuttings can then be suctioned into the interior 38 of hopper 35 via one of the openings 36, 37 in top plate 16. This can be accomplished for example using a plate 72 attached to a selected opening 36 or 37 in the top plate of hopper 35 as shown in figure 7.
  • Plate 72 has fittings 73, 74 for quick coupling and connecting respective inlet and outlet hoses 75, 76 to plate 72 when the hopper 35 is to be subjected to a vacuum.
  • the inlet hose 75 is a suction hose for intake of drill cuttings.
  • the discharge hose 76 connects to a vacuum source.
  • Such a vacuum arrangement for vacuum of drill cuttings to a collection tank is shown and described in my prior U.S. patents 5,402,857 and 5,564,509 each of which is hereby incorporated herein by reference.
  • drill cuttings are delivered to a cuttings receiving area (not shown) after having been separated from the well drilling fluid to enable the fluid to be recycled.
  • An intake portion (not shown) of the inlet hose 75 is arranged at the receiving area to suction the drill cuttings and deliver them to the hopper 35 when a vacuum is created in the hopper 35, for example by connecting the outlet hose 76 to a vacuum source such as a blower with the air inlet valve 52 and cuttings outlet valve 59 closed. Liquids and solids may be prevented from entering the blower or similar power source by positioning a separating vessel in at least one of the vacuum lines, for example outlet hose 76.
  • the flow velocity in the suction line 75 is in the range 100 to 300 feet per second with a vacuum of between about 16 to 25 inches of mercury. These are examples of typical values of the flow and vacuum and it will be understood that these are subject to variation according to the requirements for optimum performance of the invention in a given application.
  • the cuttings are discharged from the hopper 35 and transferred to vessel 82 via line 81 when the outlet valve 59 is opened.
  • the air inlet valve 52 may be opened to connect a source of pressurised air to the upstream end of the manifold 50. In this way, the cuttings are displaced towards the downstream end of the manifold 50 where the outlet valve 59 is connected.
  • discharge of cuttings from the hopper 35 may be assisted by suction in the line 81 by connecting an air line to the spool piece 66.
  • the present invention provides apparatus and method for use in handling cuttings generated during drilling operations that avoids or reduces the problems associated with the prior art. It will be understood, however, that the foregoing embodiments are presented by way of example only and that the scope of the invention is to be limited only by the following claims.
